I'm new to this and admittedly not very knowledgeable on the facts and history but I'm trying to change that.
My thinking is with the British / French mandate, the UN Partition, The 6 day war that was initiated by Israel that it was a Zionist invasion and occupation of Palestinians territory.

I don't know the history prior to WW1, but do understand that the area was part of the Ottoman Empire for 600+ years prior.

I don't know what justification Israel has for claiming this territory as their own.

Read The Thousand Year War. It's written more for a young high-schooler but it still has great information and is not a tome. It will fill in information you've never heard. You can get it cheap used too.

You can use that in conjunction with watching the old movie which just makes events real. It at least shows the betrayal by the British to the Arabs which T.E. Lawrence witnessed because he worked for British intel and fought with the Arabs. It's actually a great flick.

Then watch the movie "Exodus" to see it from the Jewish side, which shows how they were friends with Arabs and how the UN partition divides them.

Remember the UN was spawned by the US originally. It replaced progressive Wilson's League of Nations.
